This is the first time I've ever written a Critique, but here goes nothing:This comic isn't half bad! If there are any problems with this, there is one I can't help but notice: although Rainbow Dash baring her teeth in the 5th & 6th panels is a coherent expression, the teeth are being shown distinctly; isn't her mouth being covered by her mask?Other than that, though, your dialogue, consistencies, structure and twist give this the makings of the next TV show episode. I just love how they're trying to get Fluttershy to join them, but then as Rarity warns her to make good on her promise, Rainbow Dash scoffs at the marshmallow costume she was subjected to wear, and they're off! I only wish more episodes of the actual Ponies TV Show could be this funny.Oh, and nice job modifying the vectors. Keep up the good work.
